Great dog bed.  Super comfy and made very well.  My dog loves it!  Although, you can tell by one of the pictures, she's using it wrong LOL!  Slip cover is super soft, almost a velvet type fabric and comes off for easy cleaning.  The bottom has a fabric that helps it grip the floor so it doesn't slide around easily.  Smart design with Serta quality.  One of the best dog beds I've seen in a long time.  Will definitely purchase again if I need another one.
